[CentOS] where is tunctl

I am following directions in 
http://wiki.centos.org/HowTos/KVM#head-c02a0b33e7949b0bc3b151ac6e0bdfb91b6bbd1c
it says do yum install bridge-utils - works fine,
they yum install tunctl does not find anything.
yum provides "*/tunctl" does not find anything

I am using 5.4 x86_64.

Is this howto out of date?
How do I get tunctl?

Thanks,

Jerry
